this might need to be done urgently after all, because moly is having serious networking issues (in #32762 (moved)), stay tuned.

I may need a little help on this. Where are the backups or where can i see what is being backed up, to spot problems?

That's a good question! Backups are done on our central backup server, using the "Standardbackup" job, which uses the "Standard set", which looks like this:

FileSet {
  Name = "Standard Set"
  Ignore FileSet Changes = yes
  Include {
    Options {
      signature = SHA1
      compression = GZIP9
      aclsupport = yes
      xattrsupport = yes
    }
    Options {
      wild = "/swapfile*"
      exclude = yes
    }
    File = "\\|/usr/local/sbin/bacula-backup-dirs"
    # Dont backup directories that contain .nobackup files
    Exclude Dir Containing = .nobackup
  }

  Exclude {
    File = /.fsck
    File = /.journal
    File = /dev
    File = /home/buildd/build-trees
    File = /lib/init/rw
    File = /nonexistant
    File = /proc
    File = /srv/chroot
    File = /sys
    File = /tmp
    File = /srv/apache-cache/mod_cache_disk
    File = /var/cache/apache2/mod_cache_disk
    File = /var/cache/apt
    File = /var/lib/apt
    File = /var/lib/bacula
    File = /var/lib/munin-async
    File = /var/lock
    File = /var/log/samhain
    File = /var/run
    File = "\\|bash -c 'grep -s -v ^# /etc/bacula/local-exclude || true'"
  }
}

That file parameter tells Bacula to call a script to see which files to backup, and that script on majus returns:

root@majus:~# /usr/local/sbin/bacula-backup-dirs
/
/boot
/srv

So basically everything backed up on this server, with the notable exception of that Exclude list.

or shall I may a list of what I think should be moved?

That might be useful, I'm not sure. Maybe it's best if hiro or I just copy everything to the new server, unless you see a reason why we should make it different?

Also, are we going to have some puppet thing running the new server?

I'm not sure what you're asking here... Like all TPA machines, we do have Puppet running on this server and it will also run on the next one. We don't, however, have any specific configuration for translation in Puppet for Majus, so everything is configured by hand on this server.

I would be happy to integrate more Puppet stuff on this server, exactly to work around issues like the ones we faced this week. If more components of the service were in Puppet, it would be easier to restore the service: just run Puppet to recreate the service and restore only the data, as opposed to doing a barebones backup restore which is a more complex operation.

I hope that answers your questions!

Let's move it to gnt-fsn

emmapeel, sysrqb: can we just move the host to a new location and IP address or do we need to coordinate with you as the translation people?
